[Healeys] BN1 PCV system

[WILLIAM B LAWRENCE]

Harold, that is exactly what I have done. The PCV valve is located behind the exhaust manifold and pulls from the crankcase through a flange attached to the down tube location. It feeds into a fitting brazed to the bottom of the carb balance tube. It is invisible to casual observation. I have installed H6 carbs with 2-1/2 inch velocity stacks and covered them with a single piece Pipercross foam air filter. The vent to the valve cover comes out of the rear of the air cleaner between the carbs. I don’t know (or really care) if it has reduced any emissions, but I’m not getting oil into the air cleaner anymore.

Michael--

I certainly can't give you an opinion more qualified than your own but will be interested to hear how it works out for you.

After months of deliberation I have constructed this PCV system for my BN1.
The original road draft tube has been plugged just below the PCV valve takeoff.
Of importance was that the system would be almost impossible to see without very close inspection.
I'm still trying to decide if I should plug the normal valve cover vent or leave it open to serve as the PCV system intake.
Thoughts?
